Also... The teenage villains are SOOOO adorable!!! Sombra and Chyrsalis look like a brother/sister combo and Discord(looking adorable himself I might add) Looks like he's just thoroughly enjoying the show.

A shameless rip-off of "Babs Seed", I see Seriously though it's a pretty funny piece, for those that are familiar with the show (the episode mentioned specifically)... only why is Celestia's mane pink?

Because it's become fanon (based on the picture of her from the season 1 premiere storybook that showed her with a pink mane) that her mane was pink before it went all sparkly pastel rainbow? (After we all know Luna's is light blue when it's not sparkling like the night sky.)
